at Cincinnati, the underlying part would have been about 50 
feet thick. 
Time has dealt unkindly with Professor Orton’s type section 
of the Point Pleasant beds. Formerly the stream passing between 
the quarries above the road level, a half mile west of Point Pleasant, 
exposed a very fair section down to the river level. Then a larger 
culvert was put in and the exposures gradually became covered. 
At the time this section was investigated by Professor Joseph F. 
James, (On the Age of the Point Pleasant beds)^ there was a very 
fair exposure of the strata from ii feet above the river level to 
22 feet above the river level. Between 22 and 34 feet, there Was 
enough exposed to give some idea of the material forming the sec- 
tion. The beds nearer river level, some of which formerly 
had been quarried, but only at very low water, had been covered 
up and the debris at the culvert, the wash of the stream having 
been checked, covered up the upper part of the section. Professor 
James unquestionably was correct in assigning the lower 50 feet 
of the Point Pleasant section, from the level of the culvert down to 
river level, to the Point Pleasant beds. The rocks exposed above 
the road level must have been interpreted as River Quarry beds 
by Professor Orton. 
It remains now only to determine what the Point Pleasant beds 
of Orton are in terms of sections described elsewhere. The only 
statement that can be made at present is that Callopora multita- 
hulata, a species of Pras.opora, probably Prasopora simulatnx, 
Tjygospira recurvirostra^ Dalmanella hassleri, Strophomena vicinUy 
a species of Platystrophia, and Plectamhonites sericea occur imme- 
diately beneath the Point Pleasant section, at Carnestown, Ky. It is 
possible that Callopora multitabulata formerly may have occurred 
even at very low water level at Point Pleasant itself, since it occurs 
a little above river level at the landing at Ivor. At present I know 
of this combination of fossils only in the Paris bed. Strophomena 
vicina has not been found in the Greendale or Wilmore beds, 
although occurring in the Paris bed and also at the Flanagan hori- 
zon. Callopora 7mdtitabulata is known both from the Paris bed 
and from the Wilmore bed but not from the Greendale bed. This 
is true also of Prasopora simulatrix . Platystrophia is known both 
from the Greendale and the Paris beds, and there is no reason
